UNITED STATES PATENT QFFI CHARLES E. WARREN, OF LOS ANGELES, CALIFORNIA.

TEA-KE TTLE ATTACHMENT.

$PECJCEIGATION forming part Of Letters Patent N 0. 679,928, dated August 6, 1901.

Application filed October 26, 1900. -Serial No. 34,483. (No model.)

To all whom it may concern: I

Be it known that 1, CHARLES E. WARREN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, (whose post-office address is 1100 WestWashington street, in said city,) have invented certain new and useful Improvements in Tea-Kettle Attachments, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an attachment to the bottom of tea-kettles and other liquidheating vessels, whereby the heating-surface is enlarged; and my invention consists of certain features of novelty hereinafter described and claimed.

Figure I is a perspective view of a tea-kettle having my improved auxiliary heatingbotto m attached thereto. Fig. II is a transverse section taken on line II II, Fig. I. Fig. III is a section taken on line III III, Fig. II.

Referring to the drawings, 1 represents the body of the tea-kettle; 2, the spout, 3, the lid, and 4 the handle.

5 represents the flat bottom of an ordinary 6 of the auxiliary bottom is secured, as shown" at 9, to the body of the tea-kettle by any approved means.

10 represents the heating-plate of the auxiliary bottom, which is bent into a series of corrugations 11, thus forming aseries of heating-grooves 12 and a corresponding series of water-containing grooves 13. By means of the plate 10 being bent into corrugations, as described, a much greater heating-surface is attained than in the use of the ordinary bot-- tom 5 as a heating-surface. The bead 7 ,which forms the outer lower arm of the auxiliary bottom, extends a short distance below the bottom of the corrugations 11, thus confining the heat within the corrugations.

The plate 5 is provided with a series of perforations 14, which permit the water and steam to pass from the auxiliary bottom into the main chamber 15 of the vessel.

I do not confine myself to the use of the auxiliary bottom on tea-kettles, as it may be used on other vessels, if found desirable. It may be used either as an attachment to the ordinary flat-bottom vessels or it may be constructed new when the balance of the vessel is constructed.

I claim as my invention- 1. As a new article of manufacture, an attachment for vessels consisting of a peripheral plate adapted to receive within its upper edge the lower end of the vessel and to support said vessel, and having its lower end curled into a supporting-bead, and a corrugated heat= ing-plate having upwardly-opening grooves for receiving liquid and downwardly-opening grooves for retaining heat, the corrugations extending across and having their ends closed by said peripheral plate the liquid-contain ing grooves communicating with a free space extending above all of them.

2. In a tea-kettle the combination of a body having a flat perforated bottom, a peripheral plate or flange receiving the bottom of the tea kettle within its upper'edge and supporting said tea-kettle, and a corrugated auxiliary bottom secured at the sides and ends of the corrugations to said peripheral flange or plate, having the ends of the corrugations closed by said flange or plate and upwardlyopening grooves of the corrugated bottom communicating with a free space extending above all of them and adapted to hold water and the downwardly-opening grooves adapted to receive and retain heat; substantially as herein set forth.

CHARLES E. WARREN.
